Sleep deprivation makes weight loss harder. Track both.

How sleep affects weight
Poor sleep increases hunger hormones (ghrelin), decreases satiety hormones (leptin), reduces willpower, and impairs glucose metabolism. People who sleep less than 6 hours consistently gain weight faster than those who sleep 7 to 8 hours.
What to track
Log Sleep (duration, quality) and Weight daily. Add Nutrition and Exercise for the full picture. Over 4 to 6 weeks, the trend becomes clear: weeks with better sleep correlate with better weight management.
